TO ALL WHOM IT MAY CONCERN:

. Be it known that I, H. C. BERRY, of Wauseen, in the county of Fulton,and State of Ohio, have invented a new and useful Improvement in BackRest for Wood Turning; and I do hereby declare that the following is afull, clear, exact description thereof, which will enable others skilledin the art to make .and use the same, 'reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a, side view of my improved back rest.

Figure 2 is an edge view.

Figure 3 is a. view of the rest, showing its application in a lathe.

Similar letters of reference indicate like parts.

This invention relates to an improvement in a back rest for lathes usedfor wood turning, and consists in a movable segment, placed'verticallyin the lathe in place of the ordinary back rest, and provided with twoadjustable friction-rollers, which bear against the piece of timber tobe turned, and hold it steady..

Y A is a. segment, on one side of vwhich is a head or handle, a, fortting in holes or sockets in e suitable frame or standard at the back ofa lathe. Two spreading-bars B B are pivoted at the central part oi'l thesegment A near together, the outer ends of which may be expanded more orless, and are secured at any point apart by means of set-screws b b,which traverse in a slot, vc e, in the periphery of' the segment A. Onthe outer ends of the spreading-bars B vB are hung in suitable boxesfriction-rollers d cl. The whole device maybe mede of iron. l l

In order to use this device the segment A is set upright in the lathe onthe head a, with the periphery towards the front, when thespreziding-bars B B are adjustedv and fastened to the segment with theset-screws b b, so that the rollers d d shall touch'the stick of timber,and support it firmly when it is being turned, while, at the same time,there will be little or no friction. The rollers will revolve with, andnot rub on, the timber, to cause friction, and hence the wood will notbe burned, and the motion of the timber rendered uneven, as is tliecaseoften with the ordinary back rest with one rigid bearing.

Having thus described my invention, I claim as new, end desire to secureby Letters Patent- A back rest for a woodturning lathe, composed of thesegment A, in combination with the spreadlng-bars B B ond thefriction-rollers cl d, constructed andioperating substantially as andfor the purpose herein specified.
